11.   No one who lacks knowledge of a subject is competent to pass judgment on that subject. Since political know-how is a matter, not of adhering to technical rules, but of insight and style learned through apprenticeship and experience, only seasoned politicians are competent to judge whether a particular political policy is fair to all.

A major weakness of the argument is that it

(A) relies on a generalization about the characteristic that makes someone competent to pass judgment

(B) fails to give specific examples to illustrate how political know-how can be acquired

(C) uses the term “apprenticeship” to describe what is seldom a formalized relationship

(D) equates political know-how with understanding the social implications of political policies

(E) assumes that when inexperienced politicians set policy they are guided by the advice of more experienced politicians

这道题答案是：D。我可以用排除法否定其他四个选项。但是D选项这个搭桥法怎么觉得怪怪的呢？understanding the social implications of political policies文中没有直接提到啊？请多指教～

whether a particular political policy is fair to all就是social implications of political policies.

原文说，只有经验的know-how，才能解决复杂的政治问题。显然，这犯了“经验主义”错误。也就是说，结论把政治经验等同于解决政治问题。

恩，我再想想看。。。谢谢大牛牛的提点：）
